Improve the quality of cementing the 10 steps
I-type liquid slurry pumped into the time I · density J · I · mixed water filtration units control the state I-I-flow deposition and free water cement quality I · I · solid or liquid additive growth} * J · strength testing of cement laboratory and quality of the equipment. (1) slurry density slurry density higher than the drilling fluid, is conducive to flooding, but can not exceed the formation fracture pressure. (2) time in order to prevent friction and pump pressure is too high, before the end of the water pumped into the slurry can not be thickening. (3) detection of mixed water slurry mix design without considering the pollution of water, slurry thickening time and compressive strength will change greatly. Organic dissolved salts mixed in water can affect the clotting time of cement slurry, cement solidification of organic matter is generally slow, the general acceleration of inorganic cement solidification. It should detect the actual mix of cement and water well field interactions, to ensure that formula to achieve the desired effect. (4) tied to measuring the quality of the cement raw materials and cement processing plant involved in a wide range, will greatly change the quality of cement. Therefore, to test the quality of cement. (5) filtration control when necessary to prevent slurry dehydration (which will produce high-pressure pump) and filtrate losses, to join the fluid loss agent. Slurry bridge plug and the water loss may have increased the friction pressure, and density revolves. 8. Cementing the matters to be considered before these should be used as part of the routine. For example: the use of well known parameters (liquid density, pump speed, fluid rheology, casing and borehole data) in a computer simulation to determine the minimum intensity does not exceed the maximum pressure the formation sabotage the pump speed. The program also allows the operator to see the effect of different parameters of cement injection, can avoid most of the potential Other issues to consider include the t-curve state or Federal government regulations associated _ |. - Limit size well depth (vertical depth and measured depth), caliper logging, drilling fluid type and density * J-tube size, '* put down the casing pressure limit. Special casing equipment, * lithology l. ''- The direction of measurement |, · formation fracture gradient, a - formation pressure and differential pressure,:. . * Follow Wei Pu,. * The possibility of gas channeling,''* the amount of mixing water, cement type and volume, * the replacement fluid type, density and volume, * the required temperature of silica fume, * waiting setting time. '. Cementing the Vision for leek Note trickle t block do not live in assumptions, estimates, be sure to check the calculations. L ashamed of every ten workers on the job must bear in mind their double yellow''. Before the start of slurry rinse station to ensure that all devices are properly calibrated J · police equipment real-time data mining to monitor flow rate, density, pump / pump speed and pressure, helping the operator to determine the site of foreign oil and gas information, - the process of mixing units To adjust the slurry density, designed to reach the end, and can compensate for the density of air into the mixer can be adjusted by circulating Feng Wang a storage tank to achieve,
christian louboutin france, or use mixed units devices axial circulation, it can use high-energy hybrid approach mixed and pumped into the slurry. - Multi-level mixed. Ensures that all the cement into the well before the fully mixed units. Slurry residence time in the ground should take into account the thickening time, because during this time, certain characteristics of slurry will change. Now, mixing equipment,
birkenstock paris, computer control, density control in the new technology has reduced the need for multi-level mixed. 10. Assessment (blind reduced logging) the quality of the current evaluation of cementing the casing is logging or ultrasonic voltage junction chamber wells. This method can check whether the voltage has solidified cement annulus exists, providers and the density or intensity of anti-health related quality of cement. Sonic Yan Ultrasound is able to determine water consumption logging Park bond quality and the casing, the micro-rings contribute to a feast of good sensitivity too well in the acoustic Xie. The main shortcomings of this approach, one can not touch the casing of Shu Yun waterway, waterways, such as contact with the water glistening wall of water within the ring was a one can only press efficiency or annular seal, - the quality of other parts of the interpolation algorithm can only be estimated - cement voltage well explain a great deal. In actual production, cement voltage well explain the better sealing annular space is not necessarily well enough, cementing the well log interpretation, but may be more ashamed of the annular seal well. The third evaluation method that is perforated pilot. If the output of unwanted fluids,

sac hermes birkin, because, well explained if the voltage fails to determine the note attached mud still need to be perforated and workover. S boxing source I ~ fPetroleumEn ~; iaeerInter Ⅱ ation81 More articles related to topics：
