Also the theoretical basis of the method have been checked through simple deducing simulation and the influences of various physical parameters on the method have been studied . it is shown that the method is theoretically reliable for the production oil wells without very high production rate and is more suitable in field production for oil wells ( i ) in area with bigger geothermal gradient ; ( ii ) producing fluids ( oil and water ) with distinguish thermal characteristics ; ( iii ) producing oil with lower heat capacity or water with higher heat capacity ; ( iv ) with good surface measurement accuracy , as well as the method h as certain requirements on the accuracy of the temperature and flowmeter logs sensors 就該產出剖面方法的理論基礎進行了簡單的正演模擬和可能影響該方法的各項物理參數進行了全面的考察，結果表明，該方法對于非高產的生產油井來說在理論上是可靠的，在實際生產中適合于( 1 ) 、油井所在地區地溫梯度較大的油井； ( 2 ) 、油水熱特性差別較大的油井； ( 3 ) 、油比熱容值偏低水比熱容值偏高的油井； ( 4 ) 、井口計量精度較高的油井，并且對井溫測井和流量測井的傳感性精度有一定的要求。 |

Through studying it is shown that in chagan sag , the geothermal gradients in the center are higher than those around the sag margin and major factors influencing the characteristics of temperature field distribution are the property of geotectogenesis and the differences in tectonic portion , lithology and underground water behaviour ; there are three types of mudstone compaction , i . e . normal compaction , undercompacition and overcomepaction ; there are two pressure systems in sandstone reservoirs , i . e . normal pressure and negative pressure systems and the strata ' s being uplifted and denuded is the key factor leading to the formation of the negative pressure system in reservoir ; and the distinctive temperature - pressure field characteristics in the sag are possessed of important petroleum geological significance in hydrocarbon source maturity , hydrocarbon generation , widening on oil and gas exploration domain and selecting exploration targets , etc 研究表明，查干凹陷中心的地溫梯度高于凹陷邊緣，大地構造性質及所處構造部位、巖性與地下水活動的差異是影響凹陷地溫場分布特徵的主要因素；泥巖壓實存在正常壓實、欠壓實和過壓實三種類型，砂巖儲層段壓力類型可分為正常和負壓兩個系統，地層抬升剝蝕是導致儲層負壓系統形成的主導因素；凹陷獨特的溫壓場特徵對烴源巖成熟、油氣生成、油氣勘探領域的擴大及勘探方向的選擇等具有重要的油氣地質意義。 |
