Logging Interpretation of S2 Formation of Moliqing Oilfield, Yitong Basin

Abstract

Based on well logging data, this study has done research of well logging interpretation of Moliqing oilfield in Yitong basin. The Second member of Shuangyang formation is the main area. The main causes of complicated oil-water relationship are as follows: 1) rapid facies change produce diverse lithology distribution, and various lithology have different electrical property standards; 2) complex tectonic characteristics of study area bring about great difficulty in oil and water layer identification, especially a series of small normal faults in deep strata. According to those above, we built logging models in order to get essential parameters firstly. Then, several units of study area were divided. Different electrical property standards were established to solve the problem of recognition of water/oil layers. In total, more than 10,000 sand bodies of 149 wells were interpreted properly, and correct rate is higher than 90%. The conclusion is that oil layers distributed in high position of tectonics. Moliqing oilfield belongs to lithology-tectonic hydrocarbon reservoir.

Experimental Study on the Influence of Gasoline Additives on Emission and Deposits of Light-Duty Vehicle

“…The experiments illustrated that emissions of vehicle could be reduced effectively and reach to new car's emission level when blending qualified additive and driving for a long distance. Compared with the results received from engine bench test, the oil saving rate seem to be small, but was correlated with the results obtained by some other complete-vehicle road testing [8]. The fuel-saving mechanism is complex.…”
