Many times of generation and expulsion of hydrocarbon caused many times of petroleum accumulation and reservoir formation, and many times of tectonic activity probably resulted in the re-distribution and complete destruction of formed reservoirs. It will help us to recognize the patterns of petroleum accumulation in Tarim Basin and direct the展开更多

Lunnan heave and its circumference areas are located on the direction of petroleum migration, and experienced three reservoir formation cycles that are divided by wave cycle: The first reservoir formation cycle is characterized by breakage, the second by alteration, and the third by enrichment. Three layers of dissolving-cave developed on the vertical in Lunnan area. Development degree of slit-cave system and their connectivity are important factors to control petroleum enrichment in the weathering crust reservoir. The area where dissolving-caves are communicated by silts and faults was a fine petroleum enrichment area, and water was often encountered in the area with isolation cave while drilling because of no oil and gas origin. The top part of the faulted-horst as a leaking area is bearing water area, and the higher part of slope nearing the top part of the展开更多
