Exploration and development experience show that there is obvious oil gravity difference between the southern part and northern part of the ＂M1＂reservoir in the Fanny oil field in the slope of the Oriente Basin, Ecuador. The American Petroleum Institute Gravity （API） values of oils in the northern part are higher than the one in the southern part of the Fanny oil field, with the values of 2.° and 10.0°-13.0°, respectively. So the primary purpose of this study was to analyze the heavy oil characteristics of biodegradation and the oil-oil correlation according to the biomarker data and the δ^13C signature of oil samples from T block. The results of the hydrocarbon gas chromatography fingermark and the inversion attribute characteristics indicated that there are fluid compartments between the ＂M1＂ reservoir of Fanny south. Finally, the models of oil-gas accumulation under the control of multiple-activities of complicated fault systems, as well as the origin of heavy oil, are contended. The early stage oils from the western part of the basin were biodegraded heavily in varying degrees in the whole basin, and the later stage oils were derived from the southern part in a large scale and were mature and lighter. Generally, oil mixing is the primary control of net oil properties, such as API gravity in Oriente Basin. We therefore predicted that the API gravity variation of oil pools radically depends on the injection amount of the later stage oil. Because of the shale barrier in the ＂M1＂reservoir of Fanny south, the later stage hydrocarbon could not pass through and contribute to increase the oil API value.

In view of the fact that the current ground wheel velocimetry of the peanut precision fertilizer control system cannot solve the phenomenon of ground wheel slippage,and signal interference and delay loss cannot be excluded by BeiDou positioning velocimetry,a set of peanut precision fertilizer control system was designed based on the threshold speed *** system used STM32.103ZET6 microcontroller as the main controller,and touch screen for setting the operating parameters such as operating width,fertilizer type,and fertilizer application *** threshold speed algorithm combined with BeiDou and ground wheel velocimetry was adopted to obtain the forward speed of the tractor and adjust the speed of the DC drive motor of the fertilizer applicator in real time to achieve precise fertilizer ***,through the threshold speed algorithm test,the optimal value of the length N of the ground wheel speed measurement queue was determined as 3,and the threshold of the speed variation coefficient was set to 4.6%.Then,the response performance of the threshold speed algorithm was verified by comparative test with different fertilization amounts(40 kg/hm^(2.,50 kg/hm^(2.,60 kg/hm^(2.,70 kg/hm^(2.)under two speed acquisition methods of ground wheel speed measurement and threshold speed algorithm(combination of Beidou single-point speed and ground wheel speed measurement)in different operation speeds(3 km/h,4 km/h,5 km/h).The response performance test results showed that the average value of the velocimetry delay distance of the BeiDou single-point positioning velocimetry method was 0.58 m,while the average value of that with the threshold velocity algorithm was 0.2. m,which decreased by 0.31 m and indicated more accurate with the threshold velocity *** field comparison test for fertilizer application performance turned out an over 96.08%accuracy rate of fertilizer discharge by applied with the threshold speed algorithm,which effectively avoided the ina

AIM To explore the etiology and pathogenesis of human primary intrahepatic cholangiocarcinoma, the expression of HBV genes and HBV-antigens was detected in the cancerous tissue and its surrounding hepatic *** HBV-antigens were detected by immunohistochemical technique and HBV genes were examined with in situ *** In 2. cases of cholangiocarcinoma, the positive detection rate of HBxAg, pre-S1, pre-S2. HBsAg and HBcAg was 75%, 40%, 40%, 10% and 0%, respectively, and in the surrounding hepatic tissues of 19 cases the positive rates were 84.2., 47.9%, 47.9%, 31.6% and 31.6%. Among 40 cases of cholangiocarcinoma, the positive rate of HBV-DNA, x gene, pre-s gene, s gene and s gene fell on 77.5%, 70.0%, 47.5%, 40% and 42.5%, respectively, and of the surrounding hepatic tissues in 33 cases, 87.9%, 84.8%, 63.6%, 69.7% and 66.7%.CONCLUSION The development of human primary intrahepatic cholangiocarcinoma bears a close relationship with chronic persistent HBV infection. Particularly, the x gene of HBV and its protein (HBxAg) might play an important role in pathogenesis of hepatic carcinoma.A large number of studies indicate a close relationship between human primary hepatocellular carcinoma and hepatitis B virus (HBV) infection, which is considered generally as an important factor in the development of hepatic carcinoma[1,2.. In human primary hepatic carcinoma, hepatocellular carcinoma is more frequently encountered, while intrahepatic cholangiocarcinoma (ChC), including hepatocholangiocarcinoma (HChC), is relatively less, being 8%-10%[3]. For a long time, the etiology and pathogenesis of intrahepatic cholangiocarcinoma have been unclear. A few reports considered it to be related to infestation with clonorchiasis sinensis[4,5], but never involved with HBV infection. We used immunohistochemical technique and in situ hybridization methods to detect HBV genes and their -related antigens in the tissues of intrahepatic cholangiocarcinoma and its surround
