塔河油田以缝洞单元为基本开发单元，平面上连续性极差，具底水但没有统一油水界面，为轻-中-超稠油多期成藏、埋藏深的低饱和弱亲油性油藏。由于油藏具有超深、超稠，高温、高压、高黏度、高矿化度、高含硫化氢的特点，给产出剖面测井的施工、解释带来了极大的困难。通过合理改造设备、选用合适的仪器、采用井径测量、涡轮流量计与示踪流量计相结合的方法，对塔河油田生产井进行了150余井次产出剖面测井，为油井措施提供依据，提高单井产量。

Fracture?-cave unit is regarded as basic development unit in Tahe Oilfield, with continuity poor in plane. There is bottom water for the oilfield, but there is no united oil-water interface. It belongs to the reservoir with low saturation and weak oil wettability, which is light-medium-ultra-heavy oil multistage accumulation and deep burial. Some features, such as ultra-deep depth,ultra-heavy oil high temperature, high pressure, high viscosity, high salinity and high H2S content, bring about a great difficulty during the operation and interpretation of production profile logging. By modifying the equipments and choosing the right instruments, combined caliper logging, turbine flowmeter and tracer flowmeter logging, production profile logging of more than 150 well times is carried out in the production wells of Tahe Oilfield, which provides a reference for the implementation of well measure and the improvement of individual well producing rate.
