- For solving the associated gas outlet, maintaining oil and gas pressure balance and increasing the output of a single oil well, the development strategy of gas injection in gas cap and horizontal well development in oil rim was proposed in Aryskum oilfield. The location, length and distance of horizontal well were optimized based on reservoir numerical simulation method. The development effect is the best when vertical position of horizontal well is located in the middle and in the middle-lower part of the reservoir (3/5~4/5 away from oil-water interface), horizontal section length is about 500 meters, and the reasonable well spacing is 500 meters. This research obtains significant economic benefits and provides a successful experience for developing the reservoir with big gas cap and narrow oil rim.
