草33块位于乐安油田东区,该块1991年投产3口直井热采试采,效果较差,加上地面原因,储量基本未动用。本次方案在精细地质研究基础上,进行水平井技术开发界限研究,充分论证了水平井开发薄层稠油油藏的可行性。实现了草33块馆陶组薄层稠油油藏高效开发。 Grass 33 is located in the east of Le’an Oilfield. The block was put into trial production in 1991 and used for direct thermal recovery of 3 vertical wells. The result is poor and the ground is not used due to ground conditions. Based on the study of fine geology, this project conducts a research on the boundaries of horizontal well technology development and fully demonstrates the feasibility of horizontal well development of thin heavy oil reservoirs. Achieved the grass 33 Guantao thin-layer heavy oil reservoir development and efficient.
